These are great shirts - the fabric is nice and the design is bright and vibrant. I'm a big guy though, so I bought them a size larger than I usually wear. So, I usually fit in 3X's, but for these I bought 4X's and they're a bit tight on the stomach. The shoulders fit well, as does the chest. If your chest is larger than your stomach, take your normal size. If you're a plus-size guy, go one size larger than you normally wear. If you do, you'll love the shirt (and get lots of compliments this Christmas).
